Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] As Figures 1 to 9 ​​The utility model provides a kind of electric mechanical lifting platform, including platform main body 1, the periphery of the outer surface of platform main body 1 is respectively fixedly installed with first circular shaft 2, the outer surface of first circular shaft 2 is movably sleeved with fence vertical pole 3, the outer surface of fence vertical pole 3 and the outer surface of platform main body 1 are movably connected, the inside of the top of fence vertical pole 3 is movably sleeved with connecting block 4, the top of connecting block 4 is fixedly installed with fence cross bar 5, the top of fence vertical pole 3 is fixedly sleeved with second circular shaft 6, the outer surface of second circular shaft 6 and the inner surface of connecting block 4 are movably sleeved, the outer surface of second circular shaft 6 is fixedly sleeved with circular wheel 7 located at the outside of fence vertical pole 3, the outer surface of circular wheel 7 and the outer surface of fence vertical pole 3 are movably connected, the inside of the top of circular wheel 7 is movably sleeved with clamping rod 8, the top of clamping rod 8 is fixedly installed with movable rod 9, the outer surface of movable rod 9 and the outer surface of fence cross bar 5 are movably connected, the top of movable rod 9 is fixedly installed with spring 10, the other end of spring 10 is fixedly installed with fixed rod 11, the outer surface of fixed rod 11 and the outer surface of fence vertical pole 3 are fixedly connected;When movable rod 9 is moved with clamping rod 8 towards fixed rod 11, spring 10 will be compressed, so that clamping rod 8 and circular wheel 7 are separated, the locking of clamping rod 8 to circular wheel 7, fence vertical pole 3 and fence cross bar 5 is released, because fence cross bar 5 and connecting block 4 are fixedly connected and connecting block 4 is movably sleeved in the inner surface of the top of fence vertical pole 3, so at this time fence cross bar 5 is pushed, the top of fence vertical pole 3 can be rotated along the outer surface of connecting block 4 with second circular shaft 6 as the axis, the bottom of fence vertical pole 3 can be rotated along the outer surface of platform main body 1 with first circular shaft 2 as the axis, so fence vertical pole 3 and fence cross bar 5 can be retracted, thereby improve the convenience of lifting platform use.

[0026] Wherein, the top of movable rod 9 is fixedly installed with circular rod 12 located in the inside of spring 10, the top of circular rod 12 penetrates fixed rod 11 and extends to the outside of fixed rod 11 and is fixedly sleeved with handle 13, the bottom of handle 13 and the top of fixed rod 11 are movably connected;When pulling handle 13, handle 13 will be moved upwards along the inner surface of fixed rod 11 with circular rod 12, because circular rod 12 and movable rod 9 are fixedly connected, with the movement of circular rod 12, movable rod 9 will move upwards together, and the cooperation of circular rod 12 and handle 13 can also limit the movement of movable rod 9.

[0027] The platform body 1 has four long slots 14 at its front corners. A connecting rod 15 is movably connected to the side of the long slot 14 away from the center of the platform body 1. A frame 16 is fixedly installed at the front end of the connecting rod 15. The rear end of the frame 16 is movably connected to the front end of the platform body 1. The outer surface of the frame 16 is movably connected to the outer surface of the fence vertical bar 3. The inner surface of the long slot 14 and the outer surface of the connecting rod 15 are both smooth, which ensures that the connecting rod 15 will not get stuck when it moves along the inside of the long slot 14 with the frame 16. The presence of the frame 16 can enhance the stability of the fence vertical bar 3 after it is unfolded.

[0028] The platform body 1 has a drive motor 17 fixedly sleeved at the middle of its bottom end. The other end of the output shaft of the drive motor 17 is fixedly sleeved with a drive shaft 18. A rotating rod 19 is fixedly sleeved on the outer surface of the drive shaft 18. The top of the rotating rod 19 is movably connected to the top of the inner surface of the platform body 1. When the drive motor 17 is started, the drive shaft 18 will rotate. Since the outer surface of the drive shaft 18 is fixedly sleeved with the inner surface of the rotating rod 19, the rotating rod 19 will rotate along the top of the inner surface of the platform body 1 under the drive of the drive shaft 18.

[0029] The rotating rod 19 has connecting rods 20 hinged to its left and right ends, and push rods 21 hinged to the other ends of the connecting rods 20. There are two push rods 21. The outer surfaces of the two push rods 21 are movably connected to the inner surface of the platform body 1, and the inner surfaces of the upper and lower ends of the two push rods 21 are movably connected to the outer surface of the connecting rod 15. When the rotating rod 19 rotates, since the connecting rods 20 are hinged to its left and right ends and the other ends of the connecting rods 20 are hinged to the push rods 21, the near ends of the two connecting rods 20 will rotate under the action of the rotating rod 19. This will cause the other ends of the two connecting rods 20 to exert a pulling force on the push rods 21, pulling the two push rods 21 to move towards each other. This will cause the connecting rod 15 to move along the inner surface of the long groove 14 under the action of the push rods 21.

[0030] The platform body 1 has a scissor arm 22 hinged to its bottom end, and a base 23 hinged to the other end of the scissor arm 22. The presence of the scissor arm 22 enables the lifting function of the lifting platform, while the presence of the base 23 provides support and fixation, thereby ensuring the stability of the lifting platform's operation.

[0031] A hydraulic cylinder 24 is fixedly installed at the top of the base 23, and the other end of the hydraulic cylinder 24 is fixedly connected to the bottom of the scissor arm 22. When the hydraulic cylinder 24 is activated, the scissor arm 22 will unfold or fold, thereby raising or lowering the platform body 1.

[0032] Working principle and usage process of this utility model:

[0033] In the initial state, the fence vertical rod 3 is in the retracted state, the scissor arm 22 is in the folded state, and the connecting rod 15 is located inside the long slot 14. In use, the operator starts the hydraulic cylinder 24 to make the scissor arm 22 unfold, thereby lifting the platform body 1, and then the operator pulls the fence horizontal rod 5, at this time, the top end of the fence vertical rod 3 will rotate along the outer surface of the connecting block 4 with the second circular shaft 6 as the axis, and the bottom end of the fence vertical rod 3 will rotate along the outer surface of the platform body 1 with the first circular shaft 2 as the axis, until the clamping rod 8 is embedded in the circular wheel 7 under the action of the spring 10, thereby locking the fence vertical rod 3, the fence horizontal rod 5 and the circular wheel 7, at this time, the fence will be unfolded, and when the fence needs to be retracted, the operator pulls the handle 13 to make the handle 13 move along with the movable rod 9 and the clamping rod 8 through the circular rod 12 and compress the spring 10, when the clamping rod 8 and the circular wheel 7 are separated, the fence horizontal rod 5 is pushed, and the fence can be retracted, thereby improving the convenience of using the lifting platform.

[0034] After the fence is unfolded, the operator starts the driving motor 17 to make the driving shaft 18 rotate along with the rotating rod 19 and one end of the connecting rod 20, thereby making the other end of the connecting rod 20 generate a pushing force on the push rod 21 to push the two push rods 21 to move in opposite directions along the inner surface of the platform body 1, and because the connecting rod 15 is movably sleeved in the inside of the push rod 21, with the movement of the push rod 21, the connecting rod 15 will move along with the clamping frame 16 on the inner surface of the long slot 14, until the connecting rod 15 moves to the outside of the long slot 14, the clamping frame 16 will be attached to the fence vertical rod 3, thereby improving the stability of the unfolded fence by means of the clamping frame 16.
